The bulldog, Spike and his son Tyke, in Tom and Jerry cartoons is often seen with a rather bear-like stance like Butch above. It helps give the bulldogs a macho swagger and Butch often has his elbows bent out so that it looks like he's in the same position a human with their fists on their waist would be.
Same with Tom and the other cats and dogs in the cartoon series. Tom becomes more and more anthropomorphic as time goes on though.
Spike and Hector, the two bulldogs and Sylvester the cat from Looney Tunes.
Most digitigrade animals (cats and dogs) in Looney Tunes are shown plantigrade in fact.
Porky Pig averts this trope in the first season of The Looney Tunes Show by having the unguligrade stance that real pigs have, but he usually appears more digitigrade or plantigrade.
The cat (e.g., Furball, Rita, Precious, and Crump Kitty) and dog (e.g., Runt, Newt, Buttons, and Barky Marky) characters from Tiny Toon Adventures, Animaniacs, and Pinky and the Brain switch between plantigrade stance and digitigrade stance Depending on the Artist or episode. Buttons is nearly always shown digitigrade like a real dog though.
Clarabelle Cow and Horace Horsecollar from the Classic Disney Shorts are an example even though more modern appearances always depict them with shoes.
You don't see their back hooves anymore and their front hooves are drawn as hands, but in their really early appearances, you could see that they clearly exemplify this trope.
The dog and cat characters from Clifford the Big Red Dog look plantigrade (but drawn with just toes on the ground) in some poses, but look digitigrade in other poses.
Same with the dog and cat characters from Krypto The Super Dog, though some dogs, like Strectcho Mutt, and many cats really are drawn as plantigrade.
Puppetry example: Big Bird in Sesame Street is a human in a suit, therefore Big Bird has the same joints as a human. Jim Henson's sketchbook shows a design that would have averted it (the puppeteer would have faced backward, so his knees seemed to bend back instead of forward), but it was deemed impractical.
Buddy and Annie the T. rexes from Dinosaur Train are examples, but most of the other dinosaurs that are supposed to be digitigrade avert this trope.
Inversion: Mice are supposed to be plantigrade, but the mice in the original Angelina Ballerina cartoon are digitigrade (all the better to dance en pointe, one supposes).
Then un-inverted in the more recent CGI cartoons, where the characters are much more human-like (including always wearing shoes).
Similarly, the Animated Adaptation of Redwall gave even the mouse characters a digitigrade stance. Made somewhat awkward by the fact that Matthias and Cornflower wore sandals that were still designed for a plantigrade stance.
Bo and Karla from Mama Mirabelle's Home Movies. The former has feet that are just toes and the latter has feet that are just hooves.
My Little Pony: Friendship Is Magic goes both ways with this. While the feet of many of the ponies don't entirely look like actual hooved feet, they do actually walk like real equines. There are a number of occasions where they appear to have "elbows" in the middle of their forelegs, though, for gesturing purposes.
Inverted with Pepper Clark, the skunk in Littlest Pet Shop (2012): She is digitigrade, while real skunks are plantigrade.
The ducks, crows, parrots, and chickens in Sitting Ducks.
Inverted with Master Splinter in the 2003 Teenage Mutant Ninja Turtles series. He generally stands on his toes, which seems to be a stylistic choice - until flashbacks show him walking on all fours in a digitigrade stance, even though rats are plantigrade.
Cartoony Foot Shape Examples:
In the Tom and Jerry franchise, Jerry's feet bear very little resemblance to the feet of real mice and the two toes he has look rather like the two toes on camel feet.
Speedy Gonzales from Looney Tunes has two-toed feet as well, but his feet look more like rabbit or hare feet with two toes.
Porky Pig normally has feet and hooves shaped like slippers.
A white-furred female cat in the 1942 Looney Tunes cartoon, "The Hep Cat" has built-in high heels for front feet and back feet.
Piglet and Eeyore from Winnie the Pooh don't have hooves, just feet.
Goofy, Max, and even Mickey and Minnie Mouse have feet that look awfully like human feet.
Mickey and Minnie also have hand and foot proportions that would be more appropriate for a Canada Lynx than for a mouse.
Nearly all Dogfaces have awfully human-like feet in fact.
Fifi La Fume from Tiny Toon Adventures is usually seen with two toes on each foot, despite being a skunk and all.
Minerva Mink from Animaniacs has feet that look a lot like human feet.
Skippy Squirrel's feet look unusually huge and catlike for a squirrel.
In Bob's Burgers, one of the horses on the very...questionable carousel from Tina's early childhood had human feet.
Cows in the Classic Disney Shorts from the mid-1920s to the early 1930s, whether four-legged or two-legged, have feet that look somewhere between cats' feet and camels' feet.
The Ren & Stimpy Show. Ren's feet usually look appropriate for a dog (aside from having three toes instead of four), but can sometimes look somewhat humanoid, while Stimpy has plantigrade toeless feet.
Literally everyone on SWAT Kats, especially T-Bone and Razor.
Unlike her live action adult puppet counterpart, Piggy from Jim Henson's Muppet Babies has more human-like feet, four toes on each foot, instead of having hoof-like feet. But in the reboot, she has hooves like her adult counterpart.
Rare Inversion: Many human characters in The Flintstones, especially female ones, have feet that are shaped rather like cats' hindfeet, including Wilma Flintstone and Betty Rubble.
Another inversion: Human characters in The Fairly OddParents! have three-toed feet that are shaped rather like cat's hindfeet.
Only when looked at from a distance. When the feet are shown close up, the feet are shown to have four toes and generally have a human like shape. Ocassionally, they will show more frightening details
DoorMouse from Team Umizoomi has rather human feet despite having only four toes.
The Shape Bandit and some other anthrops have these as well.
While the alligators of Sitting Ducks are plantigrade like real-life crocodilians, their feet look somewhat humanoid (aside from having three toes, despite alligators having four) and lack webbing between the toes.
